What is the equation for this line

Mathematics
1 answer:
pogonyaev3 years ago
6 0

The equation of the line is y=\frac{-1}{5} x-\frac{21}{5}.

Solution:

The points on the line are (–6, –3) and (4, –5).

 x_{1}=-6, y_{1}=-3, x_{2}=4, y_{2}=-5

Slope of the line:

 $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

 $m=\frac{-5-(-3)}{4-(-6)}

 $m=\frac{-5+3}{4+6}

$m=\frac{-2}{10}

$m=\frac{-1}{5}

Point-slope formula:

 y-y_{1}=m\left(x-x_{1}\right)

 $y-(-3)=\frac{-1}{5}(x-(-6))

 $y+3=\frac{-1}{5}(x+6)

 $y+3=\frac{-1}{5} x-\frac{6}{5}

Subtract 3 from both sides of the equation.

$y=\frac{-1}{5} x-\frac{21}{5}

The equation of the line is  y=\frac{-1}{5} x-\frac{21}{5}.

Could someone please explain/help me to do this using Pythagoras theorem?
alex41 [277]

Answer:

\boxed{478.02}

Step-by-step explanation:

→ First understand what Pythagoras theorem is

Pythagoras is a theorem used to find the hypotenuse (the side opposite to the right-angle) of a triangle. We would need the base lengths as well the height in order to use Pythagoras.

→ State the formula and identify the letters

a² + b² = c² ⇒ where 'a' is 380cm, 'b' is 290cm and 'c' is what we are trying to work out

→ Substitute in the values into the formula

380² + 290² = c²

⇒ Simplify

144400 + 84100 = c²

⇒ Collect the numbers together

228500 = c²

⇒ Square root both sides to find 'c'

478.0167361 = c

→ The length of the diagonal is 478.02
